C语言代码实现邻接矩阵创建无向图

好的，下面是 C 代码，用于创建邻接矩阵表示的无向图：

#include <stdio.h>
#include <stdlib.h>

#define MAX_VERTICES 100

int adj_matrix[MAX_VERTICES][MAX_VERTICES];
int visited[MAX_VERTICES];

void create_graph(int num_vertices, int num_edges) {
  int i, j, v1, v2;

  for (i = 0; i < num_vertices; i++) {
    for (j = 0; j < num_vertices; j++) {
      adj_matrix[i][j] = 0;
    }

    visited[i] = 0;
  }

  for (i = 0; i < num_edges; i++) {
    printf("Enter edge %d: ", i+1);
    scanf("%d%d", &v1, &v2);

    adj_matrix[v1][v2] = 1;
    adj_matrix[v2][v1] = 1;
  }
}

void print_graph(int num_vertices) {
  int i, j;

  printf("\nAdjacency Matrix:\n");
  for (i = 0; i < num_vertices; i++) {
    for (j = 0; j < num_vertices; j++) {
      printf("%d ", adj_matrix[i][j]);
    }

    printf("\n");
  }
}

int main() {
  int num_vertices, num_edges;

  printf("Enter number of vertices: ");
  scanf("%d", &num_vertices);

  printf("Enter number of edges: ");
  scanf("%d", &num_edges);

  create_graph(num_vertices, num_edges);
  print_graph(num_vertices);

  return 0;
}
